You shouldn't be getting LTE from the clearwire towers until the update comes out for your G2 to turn it into tri-band. Clearwire does have panels mounted on that Wells Fargo off of Huron, but I've gotten LTE from the Sprint Grant tower in that area.

That tower has been converted for a few months, I've never seen it lose LTE service since it went active though. If you check out the sensorly (www.sensorly.com) map you can get a better idea of where the towers are active.
